Definitions
- the present invention relates to a spray-drying process.
- Spray-drying is the standard method for manufacturing laundry detergent base powder.
- detergent ingredients are mixed together to form an aqueous detergent slurry in a mixer, such as a crutcher mixer.
- This slurry is then transferred along a pipe through a first low pressure pump and then through a second high pressure pump to a spray nozzle, and the slurry is sprayed into a spray-drying tower, and spray-dried to form a spray-dried powder.
- the low pressure pump needs to be positioned as close to the mixer, such as crutcher mixer, as possible. This is to avoid starvation of the low pressure pump and to ensure consistent feed to the low pressure pump.
- the inventors have overcome this problem by introducing a stream of detergent ingredient, especially viscosity increasing detergent ingredients such as alkyl benzene sulphonic acid, into the pipe between the low pressure pump and high pressure pump, and carefully controlling its flow rate and point of addition so as to control the pressure drop between the two pumps. This minimizes the pressure drop between the two pumps, enabling the two pumps to be placed further apart (i.e. allowing the length of the connecting pipe between the two pumps to be increased) whilst maintaining efficient operation of the pumps.
- a stream of detergent ingredient especially viscosity increasing detergent ingredients such as alkyl benzene sulphonic acid
- the present invention relates to a process according to claim 1.
- the process typically comprises the steps of: (a) forming an aqueous detergent slurry in a mixer; (b) transferring the aqueous detergent slurry from the mixer to a pipe leading through a first pump and then through a second pump to a spray nozzle; (c) contacting a detergent ingredient to the aqueous detergent slurry in the pipe after the first pump and before the second pump to form a mixture; (d) spraying the mixture through the spray nozzle into a spray-drying tower; and (e) spray-drying the mixture to form a spray-dried powder, wherein the pressure drop between (i) the pressure in the pipe at the outlet of the first pump to (ii) the pressure in the pipe at the inlet to the second pump is less than 8x10 5 Pa., preferably less than 6x10 5 Pa., or less than 5x10 5 Pa., or less than 4x10 5 Pa., or less than 3x10 5 Pa., or less than 2x10 5 Pa., or even preferably less than 1x
